What is thyroid?

Thyroid is an endocrine gland which is in the shape of a butterfly and is located in the front of the lower neck. Thyroid gland has many functions, but the most important function is to produce thyroid hormones. The essential thyroid hormones are:

  • Triiodothyronine (T3)
  • Thyroxine (T4)

Apart from these there is also another hormone called thyroid stimulating and produced by the pituitary gland which stimulates the thyroid gland to produce thyroxine. These are the hormones which are being produced by the thyroid gland and with blood these hormones are carried forward to every tissue in the body.

These thyroid hormones help in regulating your metabolism, body temperature, energy, weight and mood.

What is the Thyroid profile test?

The Thyroid profile test is a combination of thyroid test which aids to determine how appropriately your thyroid gland is working, by evaluating the levels of the thyroid hormones in your blood.

What is hypothyroidism?

Hyperthyroidism is a condition where your thyroid gland becomes overactive for which your thyroid gland produces too much of thyroid hormones than your body’s requirements. Graves’ disease can cause an overactive thyroid gland.

Every laboratory provides their reference ranges within the test result, but the reference ranges varys from lab to lab. However, the typical result interpretation would be:

  • A high T3 level indicates that you may have hypothyroidism which is associated with hyperthyroidism.

The interpretation is a typical interpretation, but you should consult with your doctor about what the test result specifically indicates for you. If you have an abnormal test result, they will prescribe you additional tests to confirm a diagnosis.
